Shakespeare’s observation of our commonality is profoundly expressed by Shylock in the famous speech to his protagonists in the comedy ‘The Merchant of Venice”.
Our commonality is descriptive of all human consciousness.
Each and everyone provides their share.

Connection to reality is measured by observation of absolutes or principles.

There is no special difficulty connected with being an idealist in the imagination; but to exist as an idealist is an extremely strenuous task, because existence itself constitutes a hindrance and an objection. Soren Kierkegaard (1813 – 1855 Existentialist).

Man is not the most majestic of the creatures; long before the mammals even, the dinosaurs were far more splendid. But he has what no other animal possesses: a jigsaw of faculties, which alone, over three thousand million years of life, made him creative. Every animal leaves traces of what he was. Man alone leaves traces of what he created. The Ascent of Man. (1973) J.Bronowski

All members of the human species have consciousness available
to them in measurable degrees. Our cognitive abilities are measured
by our progress. Each and every achievement initially has been an
experience of pure cognition of ‘what is”.
Consciousness is an integral part of our commonality not a bespoke
possession of any individual.
